Chai and lactose intolerance.

the opoponax

If it helps at all for the only mildly lactose intolerant, there really isn't all that much milk in chai. My roommate makes a pot (3 or 4 cups) every morning, and only uses 1/2 a cup of milk, tops. Which means you're getting an eighth of a cup of milk in your cup of chai (that's a full American mug, no idea what the standard size is in India). If you can take your coffee with milk (and definitely if you can handle a cappucino, latte, or cafe au lait), you can drink chai.
